Can someone please explain or help me figure this white smoke coming out my exhauste at idle. It seems to come and go. I have a 50trim dbb and all the suupporting mods. I have no cats. It is fine when driving but when I come to a stop there comes the white smoke.
Someone told me it is because of the oil feed to the turbo, and the opening is too big causing excessive oil burn off at idle? Does this make sense?
Thanks

who's kit are you running?

sometimes it is recommended to run a reducer on the lines.. but its really up to your kit mfg'er.

When I had white smoke on mine it was during decel and it was tiny that it wasn't an issue. although it is sometimes referred as the first signs of your ring landings going bye bye.

the reducer is the 90* fitting that screws into the top on the turbo where the braided oil line connects......if you have an agp kit you automaticly have this reducer.....some turbo's do require a smaller restrictor but it "may" damage the turbo

Ok so which 90 is it, above the turbo or below. Also I wanted to say that I might not even have a restrictor on there, being because my kit was peiced together by a local shop. Now I am thinking maybe he did not use the one agp uses?
You said it is universal? Where do I get this part at?
Thanks for all your help!

It is all coming back to me now, originally I did want the agp kit and my local shop said he would make one up for me. So basicallly the turbo is a garrett 50trim dbb and I am sure the lines and fittings are prob his stuff he peiced together.

Ok I will get them on here tonight as I am at work right now. Did a search and many other people are having the same problem.
The brass fitting directly on top of the turbo assembly that receives oil from the engine is sucking too much oil into it because the hole on top of the fitting is TOO BIG, and the turbine wheel is throwing this oil into your O2 housing, so the oil burns up and comes out of your tailpipes.

there saying that i need to get the same fitting for the top but with a smaller hole. does this sound right??

thats exactly the problem......but there has been plenty of people that have installed this reducer with the smaller hole and blew the bearings out from oil starvation

With that being said, I have to just live with the smoke then? I mean, I do not want to blow my turbo, will first things first. I will check and take pictures of the reducer that is on there, if one is on there at all.

just to be sure what you can do is just take the turbo off and tilt it on its side.its only a few bolts. it took me 30 minutes to do it. if it leaks then that seal is bad. if no leak then it will be your reducer not being large enough. i would contact Jon @AGP and see what he says.

Which side should I tilt it? Not quit sure what you mean? I do see alot of orange RTV on my fittings!
I also read these tips from AGP:
Things to check:

Make sure there is no RTV, silicone, or any type of sealer on the oil drain flange at the turbo.
Make sure the oil drain tube is free from any kinks and it is a straight shot to the pan.
Make sure you have proper crankcase evacuation. Check your PCV, and any "catch cans" you may have installed. Any sort of extra crankcase pressure will not allow the turbo to drain properly.
